BOTTLE-PUIVI P.

SPECIFICATION forming part ofv Letters Patent No. 452,643, dated May 19,1891.

Application tiled December 15, 1890. Serial No. 874,776. (No model.)

'To @ZZ whom it may concern.-

Miamisburg, in the county of Montgomery and State of Ohio, have inventedcertain new and useful Improvements in Bottle-Pumps, ot' which thefollowing is a speciiication.

rlhis invention has for its object to provide a novel apparatus adaptedto be attached to the neck of an ordinary bottle for the purpose offilling and emptying the latter, the construction being such that acollapsible bulb or sphere in connection with an angular spout fulfillsthe conditions required for filling the bottle and subsequentlydischarging the contents thereof. rloaccomplish this object my inventioninvolves the features of construction, the combination or arrangement ofdevices, and the principles of operation hereinafter described andclaimed, reference being made to the accompanying drawings, in which theligure is a vertical central sectional vieW of my improved apparatusapplied to a bottle.

In order to enable those skilled in the art to make and use myinventionI will'now describe the same in detail, referring to the drawing, whereThe numeral 1 indicates a bottle having a neck 2, of ordinaryconstruction.

The numeral 5 indicates a chambered pumpbase, having a pendent tubularneck 4, surrounded on its exterior bya gasket 3, adapted to litair-tight into the neck of the bottle. The chambered pump-base may becomposed of hard rubber or ot' metal and is provided at its upper endwith a cup-shaped liange 12, receiving and conforming to the shape of anelastic bulb or sphere 6, having at its top portion an air-orifice l0,and at its bottom.

portion secured to the chambered pump-base by a iianged screw-threadedthimble 11, passing through the Wall of the elastic bulb or sphere andengaging a central screw-threaded Socket 13 in the pump-base.

The angular filling and emptying spout S of the apparatus is fittedair-tight in the side Wall of the chambered pump-base and is providedwith a pendent branch pipe 1i, which extends downwardly through thetubular neck 4 of the pump-base. The angular spout, by being fittedair-tight into the side of the chambered base, is attached thereto andcarried thereby, and consequently is maintained at all times in properposition relatively to the pump-base for proper action in iillin g andemptying a bottle. The construction of the pump-base enables the elasticbulb or sphere to be secured thereto through the medium of the lian gedscrew-threaded thimble 11, While the cup-shaped flange 12 constitutes aseat for the bulb or sphere and supports it against undue strain.

The lower extremity ot' the branch pipe 14 is provided with a rubbertube 9, containing at its lower end a supplemental pipe 7, Whereby theiillin g and emptying spout can be made longer or shorter for thepurpose of applying the apparatus to bottles of different size.

In the practical use of the apparatus, if it is desired to lill thebottle, the bulb or sphere 6 is compressed and a iinger or thumb isplaced over the airbrilice 10 to close the latter. The spout Sisinserted into the receptacle containing the liquid to be supplied to thebottle and then pressure is released from the bulb or sphere, so thatthe latter expands to its normal capacity, thereby causing a partialvaeuum and producing a siphon action through the spout. After the siphonis started the liquid continues to licw from the receptacle into thebottle so long as the spout is immersed and the air-orifice is uncoveredto permit the escape ot air. It will be observed that the valvelessair-orifice and valveless spout and pendent tube are important in thiscombination for the purpose of enabling the apparatus to be practicallyused for filling the bottle as Well as emptying the same, in whichrespect my invention differs from prior apparatus of this kind. Vhen itis desired to discharge the liquid from the bottle, a finger or thumb isplaced over the orifice 10 to close the same and the bulb or sphere iscompressed, Which acts to force the liquid from the bottle out throughthe spout.

Having thus described my invention, what I claim is- A bottle illing andemptying apparatus consisting of the chambered base having at its upperendl the cup-shaped flange and screw-threaded socket and at its lowerend a pendent tubular neck entering the bottlelmouth, an elastic bulb orsphere seating in the IOO Cup-shaped Mange und provided in its upper lwhereby :L bottle may be tilted :1nd emptied, io portion with fwaivetessnir-o1'ifiee,theflanged lQubtzmtially :is described.
